The Hamilton C-Line syringe minimizes the potential for bent needles with a keyed flange design.

C-Line syringes incorporate several unique design features that ensure superior performance

An improperly installed syringe can cause mis-injections or bent needles due to poor alignment. The unique flange alignment design aids in installation and results in fewer bent needles while the plunger button can be adjusted to prevent plunger tip damage. An innovative direct attachment design of the needle to the barrel minimizes sample carryover. Hamilton's headspace syringe is specifically designed for the CTC CombiPAL GC autosampler system. The High Dynamic (HD) plunger has been optimized for higher throughput in headspace techniques. These syringes feature a new sealing system based on a novel metal spring allows working with enhanced tightness, excellent performance over a large temperature range and temperature gradients, increased lifetime compared to traditional headspace syringes and ncreased accuracy and reproducibility of headspace GC analysis.

Syringes in this category are either 700 and 7000 series Microliter™ or 1700 and 1000 series Gastight® syringes. Microliter™ syringes have a stainless steel plunger that is hand fitted to the glass barrel and are designed for liquid sampling. Gastight® syringes have a PTFE plunger tip that creates tight connection between the syringe barrel and plunger allowing for liquid or gas sampling.

Compatibility: The latest generation of Hamilton autosampler syringes is recommended by CTC for use in the popular GC PAL systems: PAL GC-xt, PAL COMBI-xt, PAL COMBI-xt extended.

C-Line Syringe Terminations: Cemented Needle (N)- For low volume syringes, the needles are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. Not autoclavable. Needle gauge is determined by the syringe volume and is not user-selectable.
Special Cemented Needle (SN) - Shares the same characteristics as a standard cemented needle syringe but comes in a special length.
Knurled Hub (KH)- Removable plunger/needle assembly, knurled hub is used exclusively on the 7000 series syringes.
Headspace Syringe Terminations: Luer Tip Cemented Needle (LTN)- For mid volume syringes the needles are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. Not autoclavable. Needle gauge is determined by the syringe volume and are not user-selectable.
Needle Point Styles: Point Style 2 - Sharp, beveled, curved, non-coring needle point recommended for septum penetration.
Point Style 3 - Blunt needle point for use with HPLC injection valves and for sample pipetting.
Point Style 4 - Standard 12° beveled needle point is recommended for life science applications. Special point styles such as 45° or any other angle are available upon request.
Point Style 5 - Conical needle with side port for penetration of septa, thin-gauged vinyls and plastics without coring. Available gauges: 26-10.
Point Style AS - Special conical style needle point used on autosampler syringes the non-coring needle point is recommended for septum penetration. Available gauges: 26-10.
